SPECIFICATION forming part of Letters Patent No. 617,269, dated January3, 1899.

Application filed February 12, 1398. Serial No. 670,087. (No model.)

To all whom it may concern:

Be it known that I, GEORGE E. ADAMS, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inseparable Fasteners; and I hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification, and to theletters of reference marked thereon.

This invention relates to improvements in separable fasteners such asare used on garments, gloves, and the like, and has for its object toprovide a fastener having but few parts and in which the resilientretainingarms shall have a large range of flexibility and at the sametime be protected against breakage by external pressure--as, forinstance, as might be brought to bear upon them if stepped upon.

Referring to the accompanying drawings, Figure 1 is a perspective viewlooking at the inner side of a socket member constructedin accordancewith my present invention. Fig. 2 is a cross-sectional view through thesame. Fig. 3 is a cross-sectional view through the socket member beforeits application to the garment or web to which it is to be applied. Fig.4 is a similar view showing the form of the cap member and eyelet beforethey are secured together.

Like letters of reference in the several figures indicate the sameparts.

The letter A indicates the web or garment to which the fastener is to beapplied, and the letter B indicates the cap-piece of the socket member,which cap -piece is made crowning in cross section, and its edge isturned back upon itself, as shown atb in Fig. 4:, thence conformingapproximately to the shape of the cap-piece for a short distance towardthe center, as at b, from which point the edge converges outwardly andis divided into a series of resilient arms C, having their extremitiesturned back upon themselves at c. The converging resilient arms C form achamher or cavity for the reception of the stud member, as will bereadily understood, and

in order to secure the cap-piece or combined cap-piece andstud-receiving chamber to the web or garment I provide an eyeletD,having an outwardly-turned flange dat the top made to fit within thedoubled edge I) of the cap-piece and to have said doubled edge bent inupon it and around it, as shown clearly in Fig. 3. The member as thusformed is ready to have the eyelet passed through the goods or fabric towhich it is to be applied, and then by spreading the end of the eyeletit is secured firmly in place. In the preferred construction, however,before the edge of the eyelet is spread and turned back upon the goods asmall washer F is placed upon it to afford a continuous bearing for theedge of the eyelet and an extended gripping-surface between which andthe doubled edge of the cap-piece the goods may be gripped. By referenceto Fig. 2 it will be seen that when the socket member is thus securedupon the goods it occupies a position practically within the thicknessof the goods, or if the goods are thin it projects about equal distanceson each side. Thus it has the advantage of being an exceedingly thinorflat socket member, and in addition it will be observed that theresilient arms or holding portions are entirely protected by the strongwalls of the eyelet and doubled edge of the cap-piece, whereby they areprevented from being destroyed by accidental external pressure, and,furthermore, the resilient arms are limited in their outward movement bythe walls of the eyelet, and hence excessive lateral strain will notpermanently bend them out of shape or render the device inefficient as aholding member of a separable fastener.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States of America, is-

1. In a socket member for separable fas teners, the combination with acap piece, having its edge doubled back upon itself and terminating incentrally annularly arranged resilient retaining-arms, of an eyelethaving its flange secured by the inwardlyturned doubled portion of thecap-piece and adapted to be secured to the goods by having its edgeflared outwardly to clamp the goods between the said flared edge of theeyelet andinturned doubled edge of the cap-piece; substantially asdescribed.

2. In a socket member for separable fasteners, the combination with acap piece having its edge doubled back upon itself and conformingapproximately to the lines of the interior walls of the cap-piece for ashort distance and then converging outwardly and subdivided intoresilient arms having their ends turned back upon themselves, of aneyelethaving a flange at one end secured Within said cap-piece by havingthe doubled edge of the latter bent over the flange, said socket 10member being secured in place by having the free edge of the eyeletflared outwardly, over the web or goods to which the member is applied,above the plane of the ends of the resilient arms, whereby saidresilient arms are protected against external pressure; substanr5 tiallyas described.
